These marginal edges are turned out almost'at rightangles so that they will have peripheralsurfaces adapted jointly to serve as a roller to roll the patch down on the tire, tube, or the like. 'To scrape the surface to be patched. it is onlvnecessaryb togripthe tool 1 or 3 and present oneof the disks 6 so that its teeth 7 will engage the surface 8 (see Fig. 3), to be scraped and a I draw it over suchsurface until it has ett'ec tivelycleaned and roughened the same.

The device is made up lightly and inexpensively so that it can form a part of a Scraper-repair. kit and'thus supplies along felt need by motorists and j Though I ticularity the'details of the embodiment of the invention herein shown, it is not to" be construed that I am limited thereto, as changes in arrangment and substitution of equivalentsmay be made by those skilled in the art ithout departing fronrthe inventionfas defined in the appended claims. Having thus described invention,

what I claim as new and desire-tosecure by Letters Patent, isz I 1. As an article of manufacture, a handlehaving .pivotally mounted on an end there of, a. diskedroller having a scrapersurface I along its sharply 0ut-turned marginal rolling edge. I I 2. As anarticle of manufacture, a handle having a pair of closely associated disked rollers pivotally mounted concentrically thereon and having their marginaledges sharply out-turned in opposite direction and roughened, a'sand for the purposes de scribed.
